KABUL, Afghanistan — An insurgent-fired rocket struck the military side of Kabul International Airport on Friday, the same day Secretary of State John Kerry departed the city.

No one was injured in the attack, which happened just before 9 p.m., according to a spokesman for NATO’s International Security Assistance Force. Damage was minor, with a forklift destroyed, the spokesman said.

The airport is split between the southern civilian and northern military side, which houses an air base and ISAF facilities.

It is an occasional target for insurgents. Fighters attacked the airport on July 17, firing rocket-propelled grenades and automatic weapons from a vacant building. That attack briefly suspended flights on the civilian side of the airport before the six attackers were killed, according to Afghan officials at the time. No one else was injured in the attack.
